use kev rowleys its much nicer looking. i would recommend not using the 1200 strut as there is too much stuffing around with the spacer, much easier to use the 120y strut and hub

just picked up a pair of s13 calipers for $40 so it looks like im heading down this path, i have both pairs of drum and rotor struts but am unsure after reading this which one is better to use?

ps are everyone using the bracket like the one on ebay?

thanks

I did the conversion several months ago with great success. I went with the smaller of the two brakes options offered on a S13, [CA18DET 250mm rotors]. The 13 inch watanabes fit very nicely. the Master cylinder I used was sourced from a 240Z. Std Drum brakes are still on the rear. It does require a little more leg power as its not vacuum assisted. Soon I will be fitting ebc green stuff pads to chase a llittle more bite.

I'm using the LB lancer master and booster with the S13 front brakes. Not sure what the bore is but probably 11/16.
Mind you my brake pedal doesn't move down very much if i pump it a couple of times and then start the engine. Perhaps the booster is on the way out and explains the lack of responsiveness?
Similar symptoms to your car pigdog.

wat size master are you using? if its too big and you dont have a booster it will feel like you have no brakes....ive got that problem right now with r32/33 brakes all round and a booster that doesnt work, good fun trying to pull up fast

Hey i've done the conversion using kev Rowley's caliper spacer and i also found the brakes to be not very effective - which made me think the master cylinder and caliper cylinder were in correctly matched or my brake pads were crap.
My brake pedal is high which indicates there's plenty of fluid to fill the caliper cylinder. Most people have the opposite problem of having huge four spot calipers and pedal goes right to the floor.
Perhaps the caliper cylinder is just too small? I doubt it though. Will check manual.

epic failure. conversion is now on hold, the original disks are back on until i can work out why the upgrade wouldnt work.

The best place to get them is off the silvia forums. Most of the silvia guys go for the big five stud brake conversions. They almost give away their old stuff, 'cos it's of no use to them........
I got my rotors and calipers (with almost new pads) for $20!

you can use either, i have used the slotted ca18det ones.

are these s13 sr clipers and disks or ca18 calipers and disk brakes?
also are wreckers the best place to pick these up?
